It is estimated that even with protective measures in place the Donlin Creek mine would emit hundreds of pounds of mercury a year.35 Mining operations at.

Antimony - Wikipedia

Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the.

Mobility of arsenic and antimony associated with mining and .

Abstract: Soils, river sediments and waters from former As-Sb mining sites in FYR Macedonia have been chemically analysed to assess their impact on the local environment. Soils and river sediments contain very high concentrations of As and Sb (medians 117 and 37 mg kg-1), but values are heterogeneously distributed.

Bioaccumulation of Antimony and Arsenic in Vegetables and Health Risk Assessment in the Superlarge Antimony-Mining Area, China ... kg−1 and 0.61 mg kg−1~1.73 mg kg−1 respectively, indicating that Sb in soils exerts a certain inhibition on vegetable growth, but As has little effect on vegetable growth.

Stampede Creek and the Legacy of Mining: Antimony in Stream .

The chemistry of antimony and its weathering products is complex. When the exposure of antimony orebodies to oxidizing surface environments (air) is accelerated through mining, the weathering of the sulfide-rich ores results in the release of oxidized metals (e.g. iron, copper, lead), metalloids (e.g. arsenic, antimony), and.

Mobilization of Soluble and Dispersible Lead, Arsenic, and .

We investigated the effect of an increase in pH on the mobilization of soluble and dispersible (colloidal) Pb, As, and Sb. Our hypothesis was that the addition of divalent cations counteracts the pH-induced mobilization of soluble and colloidal metal(loid)s. We determined soluble (operationally defined as the fraction < 10 nm.
